Are the rates out of control?

Last week's write-up of the latest CPI by Stats NZ included this graph. It showed how the prices of various components of central and local government charges have been behaving since 2006.


The colours aren't that easy to tell apart, but the top line is local authority rates, which appear to be on an inexorable rise, through good times and bad. The line that drops sharply at the end is 'other private transport services', where you see the big impact of recently lower ACC levies on the cost of licensing your car.

That remorseless rise in the rates bill got me thinking, so I've done a little bit of research, and here is how the rates, average weekly total earnings, and overall inflation have behaved over the same period, all rebased to 1000 in mid 2006, and all seasonally adjusted. Over the whole period, prices in general rose by 20%, weekly earnings rose by 35%, and the rates - well, the rates rose by 60%.


Maybe we shouldn't be worried. The rates, after all, are subject to some sort of political discipline, and presumably the voting citizenry either don't mind what's happened, or even asked for it, if they felt (for example) that councils finally needed to get on with building adequate local infrastructure.

But I can't help feeling that there's an argument that the electoral discipline doesn't look very binding. At a national level, it's true that politicians can generally no longer get away with bribing the electorate with its own money - there's a great deal more transparency about the costs of lolly scrambles - but is the same scrutiny as effective at local authority level? And even assuming that all is politically hunky dory, did councils really deliver a 33% real (above inflation) increase in services to us all over that period? Doesn't feel like it. And I don't see any efficiency dividend from Auckland amalgamation in the rates graph*.

I don't have the answers, but I do have a question: are rates rises out of control?

*Addendum Oct 28 - Subsequent (separate) comments have pointed out that Auckland has had one of the lowest increases in rates since 2006, and that total rates collected in Auckland have fallen since 2009, so there may be an efficiency dividend after all.

A peek behind the veil of ignorance

Last week's post about a paper that documented the remarkable level of economic ignorance amongst New Zealand's business managers seems to have hit the spot, going by page views and comments.

Comments have been somewhere on a spectrum between head-shaking bafflement and outright incredulity, with a soupçon of "how can people this ignorant stay in business?". And, mostly, I'm somewhere in that range myself.

But one commenter pointed me to something that shows managers' beliefs in a modestly less awful light. It's an earlier paper by largely the same people, 'How do firms form their expectations: new survey evidence', an NBER working paper from April of this year. The abstract is here, but the whole thing will cost you US$5 unless you 're in academia or the media or a developing economy: us common or garden bloggers have to pay up, and I did. Oh, and the NBER is funny about copyright, so here it is - © 2015 by Olivier Coibion, Yuriy Gorodnichenko, and Saten Kumar.

What this paper found is that managers may be terrible at estimating the current or likely rate of consumer inflation - no better than the populace at large, which seems rather strange for people at the business coalface - but they are rather better at knowing what producer prices are doing in their industry. Here's the graph that shows it.


The left-hand panel A shows the distribution of managers' estimates of various recent macroeconomic data - the inflation rate in their own industry, inflation overall, GDP growth, and the unemployment rate. Negative values mean that the managers' estimates are too high relative to the real number.

Managers aren't too bad at getting their own sector's inflation rate right: on average, in fact, they're bang on, though there's still quite a big dispersion around the right answer. They're reasonably good at the unemployment rate (they have it a little higher than it really is), but not so hot at GDP growth (they have it about 1.5% - 2.0% higher than reality, from eyeballing the graph). And as my previous post said, they're really bad at the CPI inflation rate, being well off the mark on average and with estimates all over the shop.

The authors show that you can explain the managers' ignorance of the true rate of inflation in terms of 'rational inattention' - life's too short to be on top of everything, and if it's not important to you, you don't bother. Equally they show that managers who think inflation is important for their business do a better job of tracking it, and as we've seen in the graph above, managers stay on top of their industry's inflation pretty well, given that they've got both the incentive and the opportunity. And the paper's authors also show that if you give managers some additional information on actual and forecast data, they improve their estimates. Managers, in sum, aren't the complete ignoramuses you might have imagined when (for example) you see their level of ignorance about the basics of what the Reserve Bank does.

But it all still leaves that basic question: why do so many managers think inflation isn't important to them, and hence or otherwise get it so wrong?

There'a clue in the right-hand Panel B. It takes the (badly overestimated) inflation estimates in the left-hand panel, and breaks them out by the sector of respondent. You can see that there's a decent proportion of people in manufacturing and trade who have an accurate idea of inflation (though even then there's a tail of people with shots that are too high). But there isn't even a semblance of getting within cooee of the right answer for the average managers in professional and financial services firms, or in construction and transport businesses.

So here's my interpretation, not the authors' (though there are also bits of the paper that point the same way, such as the bit that shows managers in businesses with more competition pay more attention to inflation). That sectoral breakdown in Panel B is pretty much along tradables/non-tradables lines. Managers in tradables sectors have to be reasonably okay at getting inflation right, as there are enough competitors (domestic and overseas) who will eat their lunch if they're systematically bad at it. And managers in non-tradables sectors don't have to be, because there aren't.

I've thought it before, and I'm thinking it again: there are a lot of businesses in non-tradables sectors who can coast on a cost-plus mentality, and I doubt if we're going to make much inroads on our national productivity issues until stronger competitive pressures are brought to bear on them.

Another blast from the past

Statistics NZ's Twitter feed just posted this fun item:


It has a link back to a piece that Stats published in 2012, 'Delving into the clothes basket - tracking women's and men's clothing in the CPI', which went back to 1924 to look at what men and women and children wore.

It's fascinating - today's girls will be pleased that they don't have to wear the woollen bloomers of 90 years ago, and today's women will be pleased they don't have to make their own clothes - and it's one of a terrific series of time capsules that Stats have unearthed and published. Last time I wrote about them, in 'The way we live now', I said that this analysis of past CPIs was "almost a complete social history in itself". It's also a great timewaster, so cancel an hour, head to my post, and follow up the links there to the various Stats publications.

For me - and here I stress this is my take, not Stats' view or interpretation - the clothes basket piece fortuitously showed the potential benefits of trade liberalisation. From the late '80s onwards, tariffs and quotas on clothing imports were lowered or abolished. The results were that clothes prices have risen much more slowly than prices more generally (as the first graph below shows) and people have been able to buy much more (as the second one shows).



And the "cost"? - "the number of jobs filled by paid employees in the clothing and knitted product manufacturing industry fell nearly 60 percent – from 9,550 to 4,120". Four million people, give or take, got a large benefit, while 5,500 people, give or take, lost their jobs. And I put "cost" in apostrophes because many - maybe all - of those people will have found other jobs, and in activities that the community values more highly than keeping a small-scale rag trade going.

It's also very likely that liberalising clothing imports was a progressive move (in the tax policy sense of "progressive" as opposed to "regressive"). At home, the household budgets of lower and middle income families, and particularly those with children, will have had one of their bigger costs reduced. And overseas, people in poorer countries will have got real jobs, instead of aid, and started down the road of economic development that will make them better off and, along the way, better customers for our exports. That's a pretty good outcome all round.
